If you know one of the solutions of higher order equation of one variable, is there a simple way to find other solutions? For example: X & # 179; + X & # 178; + x-3 = 0, it is obvious that x = 1 is one of the solutions. Is there a simple way to find the other two solutions

x^3+x^2+x-3
=(x-1)(x^2+ax+b)
In this way, the values of a and B can be obtained
Then x ^ 2 + ax + B = 0 is a quadratic equation of one variable, and X1 and X2 can be obtained
